It is preferred practice to connect one lead from each voltage transformer directly to the neutral terminal, using a fuse in the line side of the primary only. By using this connection a transformer can never be made “live” from the line side by reason of a blown fuse in the neutral side. For continuous operation the transformer primary voltage should not exceed 110% of rated value. (b) Voltage transformers connected line-to-ground cannot be considered to be grounding transformers and must not be operated with the secondaries in closed delta because excessive currents may flow in the delta. (c) See page 32, item 1 for ferroresonance considerations. Values in table are in ohms. Note: It is recommended that system line-to-line voltage not exceed the transformer maximum system voltage level. SUGGESTED FUSE FOR MODEL RATING INTERRUPTING CAP DIA.

No fuse or fuse clip is provide, but inserts for fuse clips are supplied. • A test card is provided with each unit. RECOMMENDED MINIMUM SPACINGS A = Unit to Unit or to Ground = 1.25” minimum. B = HV to Ground in air = 6.50” minimum. Recommended spacing are for guidance only. User needs to set appropriate values to assure performance for high potential test, impulse test, high humidity, partial discharge, high altitude, and other The circle diagram can be used to predict the performance of a transformer considerations like configuration. for various loads and power factors. A convenient scale of volt-ampere is shown on the unity power factor line (u.p.f) and commences at the zero or no-load locus. To use the diagram, measure the known V.A. and scribe an arc about the “Zero” locus of a length that contains the angle of the burden power factor. The point at which the arc terminates is the error locus in phase 1”X 2” Notch angle minutes and ratio correction factor.
